A tough sub for tight spaces

RetroSound designed their low-profile SUB-8100 powered sub to give you rock-solid bass in regular cab trucks, classic cars, and other vehicles that don't have room for an ordinary subwoofer. The enclosure comes in at just 3" thick, so it'll fit behind or under a seat with room to spare. A 100-watt RMS amplifier powers the 8" sub, and they're perfectly matched to give your ride the bass it's been missing. Use the variable low-pass crossover and phase switch to get the sound you want, then use the compact wired remote to adjust your bass levels on the go.

Cast aluminum enclosure

Like your vehicle, the SUB-8100 is built to last. A rugged aluminum enclosure protects the sub and amp while dissipating heat generated by heavy, extended listening. Retrosound includes mounting hardware for the sub and the remote, so all you'll need is an amp wiring kit to get great bass in your vehicle.

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

perfect for small cabins

perfect addition to the system i put in my bros 1991 standard cab c1500. before the install of the sub the sound out of the 4x6 kenwood dash and the 4x6 Polk rear just was not doing the job. IE no bass and the volume just wasn't there. The difference after adding this compact unit was astounding. I would recommend this sub to anyone with space constraints.

Better Sound For a Superduty

I just installed this in my 2002 F-350 regular cab truck. It fits great behind the seat with some modification to the plastic storage tray back there. Tim is right, it is built very solid and the adjustment knobs are high quality the wire harness is nice too, but the fuse holder is a cheap piece of crap, better to cut it out and install you own fuse. I put an in line blade style fuse right at the battery which worked great and will be easier to change if I ever have to. The sound quality is great, I have an Eclipse stereo with stock speakers so I'm not exactly going all out here, but this little sub added a fullness to my music that was missing before plus now I can turn the bass setting on the stereo down to get more volume before it starts distorting my factory speakers. I don't want to put a complete system in this truck because it is completely unmolested and there is no room, so this was a good way to get better sound. If you are looking for a license plate rattling thump thump, this is obviously not the answer.

Big sound in a little package.

All I can say is wow,what a nice sub for small car or truck.I just put it in a 1997 Nissan std cab pickup never would have thought I could fit a sub behinde the seat(most people would have put a box behide the seat and moved the seat up to make room for the sub,not me Im 6'1" and the seat in any position but all the way back is not a option)installation was simple and fast,and they matched up well with the polk 651 6.5" I installed the day before(no amp on the polk's)I was happy with just the polks but I bought the sub the same time but wanted to hear it with and without the sub. I figured if the sub gave me even a little bass I would be vary happy,well it gave me a lot of bass,couldn't be happier.
